I found a picture of my now 14 year old as a toddler.
We used to call her "The Dummy Commando" (amongst other things) As she loved a dummy at that age.
Many mums ask me if dummies/pacifiers create bad habits or a negative sleep association, many sleep experts suggest getting rid of dummies as early as possible. I really don't have an issue with dummies unlike many other experts. As long as you keep dummies as clean as possible i don't think your little one having a dummy need be a problem.
